The present report aimed to study an uncommon case of a pair of twins that presented a discordant dental phenotype. Family investigation, clinical, radiographic examination and molecular analysis were performed in both girls. Molecular analysis confirmed the monozygosity by deoxyribonucleic acid chip technology. One twin presented tooth agenesis in left upper lateral incisor and peg-shaped on t...

Chemoradiation therapy used on pediatric oncology patients often causes dental developmental anomalies that affect future dental care. Defects noted include tooth and root agenesis, root thinning and shortening, and localized enamel defects. Histologically, these defects appear as osteoid-like niches in the developing dentin which alter the overlying enamel. Odontogenic cell sensitivity is depe...

OBJECTIVES Tooth agenesis is one of the most common developmental anomalies in humans. Genetic and environmental factors may be of etiological importance in this condition. Among genes involved in tooth morphogenesis, mutations in PAX9, MSX1, AXIN2, WNT10a, and EDA genes have been associated with tooth agenesis. The aim of our study was to investigate the relationship between the PAX9 gene vari...

OBJECTIVE To determine the prevalence of mesiodens in deciduous and mixed dentitions and its association with other dental anomalies. MATERIAL AND METHODS Panoramic radiographs of 1,995 orthodontic patients were analyzed retrospectively, obtaining a final sample of 30 patients with mesiodens. The following aspects were analyzed: gender; number of mesiodens; proportion between erupted and non-...

PURPOSE The aim of the present study was to investigate the prevalence of dental anomalies in a Turkish population according to the gender and age. MATERIALS AND METHODS A retrospective study was performed using panoramic radiographs of 2025 patients (885 males and 1140 females) ranging in age from 9 to 35 (mean age 25.61±10.04) years attending Department of Oral Radiology, University of Ista...

Abstract: Agenesis is commonly found in maxillary lateral incisors with a relative high preva-lence. We reported case of agenesis the upper incisor associated dental caries. A 20-year-old man came to Unjani Dental Hospital complaint cavities left incisor. His only was lack confidence due caries; no pain. At first visit, anamnesis and clinical examination were performed on him. Oral hygiene good...

Aim Dental anomalies in shape and number may be present isolated or associated with other manifestations. In anhidrotic ectodermal dysplasia they occur more frequently and severely. The authors examined a group of children with similar dental anomalies but no other ectodermal or extra-ectodermal signs. Methods This study makes a comparative evaluation of similarities and differences of dental a...

The aim of this study was to determine the frequency of different dental anomalies in different malocclusion groups of patients seeking orthodontic treatment. This study was carried out at the Orthodontic Department of Armed Forces Institute of Dentistry (AFID), Rawalpindi. Data for the study were collected from the pretreatment diagnostic records of patients who reported at the department for ...

Tooth agenesis is the most common dental anomaly. The aim of this retrospective study was to identify common patterns of tooth agenesis in a sample of 92 patients (55 females and 37 males; mean age 27.7 years) with non-syndromic severe hypodontia. The Tooth Agenesis Code (TAC) procedure was used for that purpose. The patients in this study were missing between 6 and 22 permanent teeth (mean 11....
